Detailed Description
[ first embodiment ]
An embodiment of one aspect of the present invention (hereinafter also referred to as "the present embodiment") will be described below with reference to the drawings. However, the present embodiment described below is merely an example of the present invention in all aspects. Various modifications and changes can be made without departing from the scope of the present invention. That is, the specific configuration corresponding to the embodiment can be appropriately adopted in the practice of the present invention.
Application example § 1
First, an example of a scenario to which the present invention is applied will be described with reference to fig. 2 and 3. Fig. 2 is a diagram schematically showing the multi-optical axis photoelectric sensor 100 according to the present embodiment. As shown in fig. 2, the multi-optical axis photoelectric sensor 100 includes a light emitter 110 and a light receiver 120 which are arranged to face each other with a predetermined detection region therebetween. As illustrated in fig. 2, a plurality of optical axes are set between the light emitter 110 and the light receiver 120, and the multi-optical axis photoelectric sensor 100 detects an object based on incident light on the optical axes and a light-shielded state.
Fig. 3 is a schematic diagram of the housing 1. The housing 1 serves as a housing for the light emitter 110 and the light receiver 120. The housing 1 includes: the main body case 11, the cover members 12 and 13, the transparent plate 15, and the pressing member 20 (see fig. 1). In fig. 3, the pressing member 20 is not shown.
As shown in fig. 3, in the housing 1, the main body case 11 and the lid members 12 and 13 constitute the outer case 10. Specifically, the case housing 10 has a structure in which the lid members 12 and 13 are fitted into both ends in the longitudinal direction of the cylindrical main body housing 11 having a rectangular cross section.
An opening 14 is formed in one surface of the housing case 10. The opening 14 is closed by a light-transmitting plate 15. The transparent plate 15 is pressed against the housing 1 by the pressing member 20. In the following description, one surface of the housing 1 on which the opening 14 is formed is referred to as a "front surface". The direction from the inside of the housing 1 to the front surface is referred to as "front" or "front side".
As shown in fig. 3, the opening 14 may be formed over all of the main body case 11 and the cover members 12 and 13. However, the opening 14 may be formed only in the main body case 11. That is, the opening 14 may be formed at least in the main body case 11.
The multi-optical axis photoelectric sensor 100 can be expressed as follows. That is, the multi-optical axis photoelectric sensor 100 has an outer shape in which the light emitter 110 and the light receiver 120 are formed in the housing 1, and the housing 1 includes: the electronic device includes a housing case 10 having an opening 14 on a front surface, a transparent plate 15 closing the opening 14, and a pressing member 20 pressing the transparent plate 15 against the housing 1.
Construction example 2
Next, a configuration example of the housing 1 will be described with reference to fig. 1 and 4. In fig. 1 and 4, the width direction of the housing 1 is defined as the x direction, the longitudinal direction is defined as the y direction, and the front-rear direction is defined as the z direction. In particular, the front of the housing 1 is set to the + z direction.
Fig. 1 is a developed view showing the structure of a housing 1 of the present embodiment. As described above, the housing 1 has a structure in which the lid members 12 and 13 are fitted into both ends of the main body case 11 in the longitudinal direction.
An optical element 16 is housed inside the housing 1. The optical element 16 is a light emitting element when the housing 1 is applied to the light emitter 110, and is a light receiving element when applied to the light receiver 120. At least one of the cover members 12 and 13 is provided with a connector (not shown) for supplying power to the optical element 16 or extracting a signal from the optical element 16.
The housing 1 further has an adhesive tape 17 (adhesive material). The light-transmitting plate 15 is disposed so as to close the opening 14 from the front side of the adhesive tape 17. A pressing member 20 is attached to the front side of the light-transmitting plate 15. Specific positions of the adhesive tape 17 and the pressing member 20 will be described later.
The length of the body case 11 differs depending on the type of the multi-optical axis photoelectric sensor 100. The multi-optical axis photoelectric sensor 100 can be used by cutting the adhesive tape 17 having a sufficient length according to the length of the main body case 11, and can correspond to any length of the main body case 11.
Fig. 4 is a partial sectional view showing the structure of the housing 1. Specifically, fig. 4 is a cross-sectional view of the housing 1 on a surface including the main body case 11, perpendicular to the longitudinal direction of the housing 1. As shown in fig. 4, the main body case 11 has a pair of side plates 11a on both sides in the width direction. Support portions 11b for supporting both side edges of the transparent plate 15 are formed on the inner surfaces of the side plates 11 a. In addition, the lid members 12 and 13 are also formed with support portions (not shown) continuous with the support portion 11 b. In the present embodiment, an adhesive tape 17 is disposed on the front surface of the support portion 11 b. The adhesive tape 17 joins the transparent plate 15 to the support portion 11 b.
An extending portion 11c extending in the direction of the end of the other side plate 11a is formed at the end of each side plate 11a where the opening 14 is formed. The pressing member 20 is mounted on the extension 11 c.
Specifically, in the housing 1, the pressing member 20 includes a first protruding portion 21 and a second protruding portion 22. The first protruding portion 21 and the second protruding portion 22 face each other in the thickness direction of the light-transmitting plate 15. The first protruding portion 21 and the second protruding portion 22 are formed over substantially the entire length of the main body case 11. The first protruding portion 21 is positioned further forward than the second protruding portion 22 in a state where the pressing member 20 is attached to the extending portion 11 c. The pressing member 20 is attached to the extending portion 11c with the extending portion 11c interposed between the first protruding portion 21 and the second protruding portion 22, and presses the transparent plate 15 against the supporting portion 11 b. In particular, in the present embodiment, the pressing member 20 is attached to the extending portion 11c so as to move in a direction parallel to the front surface of the housing 1. Therefore, when the pressing member 20 is attached, it is not necessary to press the light-transmitting plate 15 with a force equal to or greater than the pressing force generated by the attached pressing member 20. Therefore, the assembly work of the multi-optical axis photoelectric sensor 100 having the housing 1 can reduce the labor required.
The pressing member 20 presses the transparent plate 15, thereby reducing the gap between the transparent plate 15 and the support portion 11 b. Therefore, the liquid such as oil can be prevented from entering the inside of the housing 1. In particular, in the housing 1 of the present embodiment, the adhesive tape 17 seals between the light-transmitting plate 15 and the support portion 11b, whereby the liquid can be more prevented from entering than a housing without the adhesive tape 17.
In the present embodiment, the distance between the tips of the pair of extending portions 11c is larger than the width of the light-transmitting plate 15. Therefore, when the housing 1 is assembled, the light-transmitting plate 15 can be arranged on the support portion 11b from the front of the case 10.
A first protrusion 11d is formed on a surface of the extension 11c facing the first protrusion 21. On the other hand, a recess 21a into which the first protrusion 11d is fitted is formed on the surface of the first protrusion 21 facing the extension 11 c. The concave portion 21a is provided corresponding to the position of the first protrusion 11d when the pressing member 20 is properly attached to the extension 11 c.
Therefore, in a case where the pressing member 20 is not properly mounted on the extended portion 11c, the first protruding portion 21 is formed in a state of being lifted up from the extended portion 11 c. Therefore, when the pressing member 20 is not properly attached to the extending portion 11c, the above-described situation can be easily recognized visually.
In the housing 1 of the present embodiment, the first protrusion 11d may be formed on the first protrusion 21, and the recess 21a may be formed on the extension 11 c. The first protrusion 11d and the recess 21a may be formed on (i) a surface of the extending portion 11c facing the second protrusion 22 and (ii) a surface of the second protrusion 22 facing the extending portion 11 c. That is, in the housing 1 of the present embodiment, it is sufficient that (i) either one of the surfaces of the extending portion 11c facing the first protruding portion 21 or the second protruding portion 22 or (ii) the surface of the extending portion 11c facing the first protruding portion 21 or the second protruding portion 22 has the first protruding portion 11d, and the other surface opposite to the one surface has the recess 21a into which the first protruding portion 11d is fitted. According to the housing 1, the position where the pressing member 20 is attached to the extending portion 11c can be appropriately determined.
The side plate 11a is provided with an engaging portion 11e that engages with the first protrusion 21 (end portion of the pressing member) on a side farther from the light-transmitting plate 15 than the extending portion 11 c. Specifically, as shown in fig. 4, the engaging portion 11e is inclined in the direction toward the center in the width direction of the main body case 11 as it goes from the extending portion 11c toward the front. The tip of the first projecting portion 21 is also inclined toward the center of the main body case 11 in the width direction as it goes toward the front in a state where the pressing member 20 is attached to the extending portion 11 c. Therefore, even if the pressing member 20 is deformed to expand the interval between the first projecting portion 21 and the second projecting portion 22 after the pressing member 20 is appropriately attached to the extending portion 11c, the possibility that the first projecting portion 21 is lifted from the extending portion 11c can be reduced.
3 modification example
Fig. 5 is a partial cross-sectional view showing the structure of a housing 1A according to a first modification. The housing 1A differs from the housing 1 in that a pressing member 20A is provided instead of the pressing member 20. The pressing member 20A is different from the pressing member 20 in that a second protrusion 21b is provided on a surface of the first protrusion 21 facing the extension 11 c.
In the pressing member 20A, the first protruding portion 21 abuts on the extending portion 11c only at the second protruding portion 21 b. Therefore, the frictional force generated between the first protrusion 21 and the extension 11c in the process of attaching the pressing member 20A to the extension 11c is smaller than the above-described frictional force in the process of attaching the pressing member 20 to the extension 11 c. In other words, the force required to attach the pressing member 20A to the extension portion 11c is smaller than the force required to attach the pressing member 20 to the extension portion 11 c. Therefore, the multi-optical axis photoelectric sensor having the housing 1A can be assembled more easily than the multi-optical axis photoelectric sensor 100 having the housing 1.
The second protrusion 21b is formed on a surface facing the surface on which the extension 22c of the first protrusion 11d is formed. The second protrusion 21b is formed to be located further outward than the first protrusion 11d in the width direction in a state where the pressing member 20A is attached to the extension 11 c. Therefore, when the pressing member 20A moves in the direction of separating from the extended portion 11c, the second protrusion 21b is caught by the first protrusion 11d, so that the pressing member 20A can be suppressed from being accidentally detached from the extended portion 11 c.
In the present modification, the surface of the first protruding portion 21 or the second protruding portion 22 facing the surface of the extending portion 11c having the first protruding portion 11d may have the second protruding portion 21 b. That is, when the first protrusion 11d is provided on the surface of the extension 11c facing the second protrusion 22, the second protrusion 21b is provided on the surface of the second protrusion 22 facing the surface of the extension 11c having the first protrusion 11 d.
Fig. 6 is a partial sectional view showing the structure of a housing 1B according to a second modification. The frame 1B is different from the frame 1 in that an elastic member 18 is provided between the pressing member 20 and the transparent plate 15. As shown in fig. 6, the elastic member 18 has a rectangular cross section. Specifically, the elastic member 18 is flat rubber, for example.
In the housing 1B, the pressing member 20 presses the light-transmitting plate 15 via the elastic member 18. Therefore, in the housing 1B, the light-transmitting plate 15 is pressed more strongly by the elasticity of the elastic member 18. Therefore, since the adhesive tape 17 is pressed more strongly, the possibility that the optical element 16 (see fig. 1) is exposed to a liquid such as oil can be reduced. Further, since the elastic member 18 seals between the pressing member 20 and the light-transmitting plate 15, the possibility that the adhesive tape 17 is exposed to the liquid can be reduced.
Fig. 7 is a partial sectional view showing the structure of a housing 1C according to a third modification. As shown in fig. 7, the housing 1C differs from the housing 1B in that (i) an elastic member 18C is provided instead of the elastic member 18, and (ii) a pressing member 20C is provided instead of the pressing member 20. The elastic member 18C differs from the elastic member 18 in that the cross section is not rectangular but circular. The pressing member 20C is different from the pressing member 20 in that a groove portion 23 into which the elastic member 18C is fitted is formed.
The groove 23 has a depth larger than the cross-sectional radius of the elastic member 18C and smaller than the diameter. The groove 23 has a cross section along the cross section of the elastic member 18C. That is, (i) the width of the groove portion 23 on the surface of the pressing member 20C is smaller than the diameter of the elastic member 18C, and (ii) the groove portion 23 has a width substantially equal to the diameter of the elastic member 18C inside the pressing member 20C. Therefore, the elastic member 18C fitted into the groove portion 23 is less likely to fall off from the groove portion 23 by gravity or the like. Since the elastic member 18C has elasticity, the elastic member 18C can be fitted into the groove portion 23 having a width smaller than the diameter of the elastic member 18C in an undeformed state by deforming the elastic member 18C by pressure.
In the housing 1C, the pressing member 20C presses the light-transmitting plate 15 via the elastic member 18C. The housing 1C has the following effects in addition to the effects of the housing 1B. That is, when the housing 1C is assembled, the elastic member 18C is fitted into the groove portion 23 in advance, so that it is not necessary to consider the position of the elastic member 18C when the pressing member 20C is attached to the extending portion 11C. Therefore, the multi-optical axis photoelectric sensor having the housing 1C can be assembled more easily than the multi-optical axis photoelectric sensor having the housing 1B.
The present invention is not limited to the above embodiments, and various modifications are possible within the scope shown in the claims, and embodiments obtained by combining technical means disclosed in different embodiments are also included in the technical scope of the present invention.

According to the above configuration, the light transmitting plate is supported by the supporting portion formed on the inner surface of the side plate of the housing case and extending in the direction of the end portion of the other side plate. Further, a pressing member is attached to an end portion of the housing case in a state where the formed extending portion is sandwiched between the first protruding portion and the second protruding portion.
The pressing member is formed in a state of being attached to the extending portion, and presses the light transmitting plate supported by the supporting portion formed on the inner surface of the housing case with an appropriate pressure.

According to this configuration, in the process of attaching the pressing member to the extension portion, since the area of the region where the extension portion and the pressing member contact is reduced, the frictional force between the both is reduced.

In the multi-optical axis photoelectric sensor according to one aspect of the present invention, the pressing member presses the light-transmitting plate via an elastic member.
According to the above configuration, the light transmitting plate can be pressed more strongly by the elasticity of the elastic member.
Further, the multi-optical axis photoelectric sensor according to one aspect of the present invention further includes an adhesive for bonding the light-transmissive plate to the support portion.
According to the above configuration, the inside of the housing can be sealed by pressing the adhesive material with the pressing force of the pressing member. Therefore, the entry of oil or the like into the housing can be suppressed.
